Hacienda Monasterio produces wines in Ribera del Duero, the Castilian region renowned for structured, age-worthy reds built on Tinto Fino and Tempranillo. The winery's Cosecha blends Merlot, Cabernet Sauvignon, and Tinto Fino into a wine that has drawn attention from Wine Spectator, Wine Advocate, Falstaff, and Decanter. The Reserva, built on Cabernet Sauvignon and Tinto Fino, follows a similar trajectory of critical engagement. A Reserva Especial, made from Tempranillo alone, rounds out the portfolio. These wines reflect the region's continental climate and slate-rich soils, which yield dark fruit intensity and tannin architecture suited to cellaring.
